Brittany Kaiser is the SECOND known Cambridge Analytica employee to be subpoenaed by Mueller. Sam Patten [business partner to Russian GRU operative & Manafort assoc, Kilimnik] has already entered into a plea deal with Mueller. Kaiser is the first figure linked directly to Brexit.

Former Cambridge Analytica employees Sam Patten [business partner to Russian GRU operative Kilimnik] and Brittany Kaiser – both subpoenaed by Mueller – were involved in the controversial Jan 2015 Nigerian election, which had “unsettling” parallels to the US presidential election.

During the 2015 Nigerian campaign, Cambridge Analytica worked alongside unidentified Israeli intelligence operatives who hacked the now-president of Nigeria’s emails and released damaging info about him to the press weeks before the election.#Maddow

Her motive for doing so is likely to come under scrutiny: this has been a catastrophic week for the firm – and Kaiser was a senior executive. She claims, however, that it is because she wants to stop telling lies.
